IMPROVEMENT IN NURSERY COOKING-RANGES.

is ecification forming part of Letters Patent No. 1 8 9,968, dated April24, 1877 applicationfiled.

v March 1 1877. i a

To all whom it may concern Be it known that I, LYMAN TOBEY, of Naples,in the county of Ontario 'and State of New York, have invented certainnew and useful Improvements in Nursery Cooking- Range; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

The nature of my invention consists in the construction and. arrangementof a nursery cooking-range, as will be hereinafter more fully set forth.

In the annexed drawings, which fully illustrate my invention, Figure lisa central vertical section, and Fig. 2 is an enlarged detail view, of myinvention.

A represents a sheet-metal table of any suitable dimensions, supportedon a base, B, by legs or braces O 0. On the base B is placed or securedan oil-reservoir, E, provided with two or more burners, D D, of anyordinary construction, each burner being provided with a glass chimney,H. Around each chimney H is a sheet-metal cylinder, G, provided at itslower end with an annular base-ring, I, and forming with said base ajacket for protecting the chimney from the cooling efiects of the outerair, and at the sametime forms a hot-air chamber, from which the heatedair passes through the circular grate J, and, combining with the directhot current from the inside of the chimney, rises to the cooking-vesselssupported by the grate.

The cylinder G may be suspended from the top of the table Aby means ofan outwardlyprojecting flange, a, formed around the upper end of thecylinder; or the cylinder may be sup ported by the base I, (eitherstationary or movable,) which base, in turn, rests on wire supports I),attached to the bottom of the burner.

The base is nearly tight, having only a few perforations, we", andtherefore prevents an excess of cold air from entering below toneutralizethe heat within the cylinder, by which arrangement the currentof air between thechimney and cylinder becomes intensely heated beforecoming in contact with the cookingvessels above, which, added to thedirect heat from the inside of the chimney, forms a concentration ofheat far in excess of that'usually obtained by the ordinary petroleumapparatus 7 for heating or cooking.

It will be seen that the base I of the cylinder is elevated, so as toallow the cold air to circulate freely around the bottom of the chimneyand the base of the burner, thereby keeping the lower part of thechimney and burner always cool, and thus preventing any danger fromexplosion by overheating the oil in the reservoir. By this arrangementthe draft of the lamp is in no wise obstructed. The base of the cylinderbeing about on a level with the cone of the burner, an amount of lightis obtained sufficient for all ordinary purposes.

The circular grate J consists of an annular plate of suitabledimensions, having a downwardly-projecting flange, 6, around its outeredge, and the inner edge is slotted radially with a series of slots,forming lips 01 d, which are bent alternately upward and downward. Thisgrate rests on top of the cylinder, and serves a threefold purpose. Itforms a support for the cooking-vessels, serves as a ventilating anddraft flue for the hot-air chamber and chimney, and it operates as aprotection to the top of the chimney by preventing the cold air fromcoming too suddenly in contact with it when the cooking-vessel isremoved.

Outside of the grate on the table Aare ribs h h, set in the table forsupporting vessels that are too large to rest securely on the gratealone. L represents one of thecooking-vessels, which may be made of anysize or shape to suit the wants of the nursery.

P is a case for cooking-vessels, .made open at the bottom, and with acircular opening in the top. This extra case is for covering thecooking-vessel L, and serves the double purpose of confining the heatfrom below, thus forming another hot-air chamber around thecooking-vessel, and also for preventing the outer cold air from comingin direct contact with the vessel itself. On the top of the case P areribs '5 i, for supporting a second vessel, and thus utilizing the heatedcurrent from below a second time.

By transferring the burner D, which has the Wire supports b, with itschimney, cylinder, base, grate, and. cooking-vessel, to any ordinarylamp-reservoir, a complete nursery-lamp is obtained, serving the doublepurpose of a night-lamp and a cooking utensil.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- 1. The annularv grate J,slotted radially around its inner edgeto form a series of lips, d,'thatare bent alternately upward and down- Ward, substantially as and for thepurposes herein set forth.

2. The combination, with an ordinary removable lamp-burner and glasschimney, of 7 two witnesses.

the cylinder G, base I, and grate J, all constructed and arrangedsubstantially as and for the purposes herein set forth.

3. The combination, with a lamp-burner and chimney, of the cylinder G,base I, grate J, cooking-vessel L, and covering-case P, substantially asand for the purposes herein se forth. x

In testimony that I claim the foregoing as my own I affix my signaturein presence of LYMAN TOBEY. Witnesses:
